Footwear Last Digital Replication for Remote Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers face challenges in finding properly fitting footwear due to inconsistencies in sizing across different models, leading to reluctance in purchasing footwear without trying it on, resulting in lost sales and customer dissatisfaction.
Innovation Solution
A method allowing customers to purchase footwear by specifying the last used in its construction, either through direct identification or by correlating customer identity with suitable lasts, ensuring proper fit through remote communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If footwear is manufactured using different lasts for different models, then footwear variety and design flexibility are improved, but sizing consistency and fit reliability deteriorate
Solution Approach 1:
The patent creates a digital copy (data structure) of the last's dimensional information, which can be stored, transmitted, and used for remote ordering. This digital replica allows customers to order footwear made to their specific last measurements without physically trying on multiple pairs, thus maintaining footwear variety while ensuring sizing consistency through precise digital replication of last dimensions.
2Manufacturing precision
If customers try on footwear before purchase, then fit accuracy is improved, but convenience and accessibility deteriorate
Solution Approach 1:
The patent performs preliminary action by having customers measure their feet and obtain their last dimensional information before the purchasing process. This pre-acquisition of sizing data eliminates the need to physically try on footwear at a store, as customers can directly order the correct size online or via remote communication, thus maintaining fit accuracy while dramatically improving purchasing convenience.
3Reliability
If manufacturers provide samples of each model in each size to every retailer, then customer fit verification is improved, but distribution cost and complexity increase
Solution Approach 1:
The patent replaces the mechanical system of physical footwear samples with an information-based system (data structure containing last dimensional information). Instead of distributing physical samples to numerous retailers, the digital last data can be electronically transmitted to customers or retailers, eliminating the need for extensive physical inventory distribution while maintaining the ability to verify fit accuracy.
4Ease of operation
If footwear is ordered remotely without physical inspection, then purchasing convenience is improved, but fit reliability deteriorates
Solution Approach 1:
The patent introduces an intermediary element - the data structure containing last dimensional information - that bridges the gap between remote purchasing convenience and fit reliability. This intermediary allows customers to remotely order footwear with confidence by providing precise dimensional data about their foot and the last, enabling manufacturers to produce accurately fitted footwear without requiring physical inspection or trial fittings.
Data Source
AI summary
A method whereby a customer may purchase footwear through a remote communication channel, and be assured that the purchased footwear will properly fit upon delivery. The customer purchases footwear by designating the last that is used to construct the footwear. A customer may identify a particular last based upon careful measurement of the customer's feet. A customer may also identify a last based upon previous experience with footwear constructed using the last.
